ABSTRACT:
An apparatus such as a television signal receiver includes first and second circuit boards. The first circuit board includes a first device such as a memory, and control circuitry for controlling at least one function of the apparatus. The second circuit board is operably coupled to the first circuit board via control lines. The second circuit board includes a controller for generating first and second control signals. The control lines transmit the first control signals from the controller to the first device when the apparatus is in a first operational state, and transmit the second control signals from the controller to the control circuitry when the apparatus is in a second operational state.
